CASPER DEVILBISS, OF SHELLSBURG, IOWA.

IMPROVEMENT IN CAR-PROPELLERS.

Specification forming part of Letters Patent No. 157,801, dated December 15, 1874; application filed October 3, 1874.

To all whom it may concern:

. Be it known that I, CASPER DEVILBISS, of Shell sburg, Benton coun ty,in the Stateof Iowa, have invented a new and Improved Mode of Constructing and Operating Railroads and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specication, in which is represented a side elevation of my improved railroad, showing; the cars thereon.

The invention will iirst be fully described, and then pointed out in the claim.

A represents a series of posts set in the ground on each side of the railroad, which support wheels B having a high ange on the outside. These wheels may have each a separate shaft, but I prefer to hang them on the ends of shafts which shall span the road, or extend from one post to the opposite post of the road. The bars O C of car-frame are made to run between the flanges of wheels B B and on their peripheries. D is the guide and friction bar, which is elevated over the middle of track, while E and F are friction-rolls between which the bar is passed. The upper roll, F, is attached to a sliding` gate, F', and made adjustable, so as to increase or diminish the friction, according to the load. rLhe lower roll is connected with and worked by the engine, which is arranged on the carin any convenient position. are turned so as to then bite upon bar D, thereby drawing` the car over the wheels B.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

lIhe car-frame, having bars O C and frictionrolls E F combined with the outer hanged wheels B and friction-bar D, as and for the purpose described.

CASPER. DEVILBISS.
